Application filed February 15, 1906. Serial No. 301,141.

To aZZ whom it may concern Be it known that we, MAXIMU IAN C. Sonwnmnnr, residing in West Hoboken, in the county of Hudson and State of New Jersey, and I-IENBY P. IKRAFT, residing in the borough of Brooklyn, county of Kings, city and State of New York, citizens of the United States, have invented certain new and useful Improvements in Water-Bottle Stoppers, of which the following is a specification.

This invention relates to water bottle stoppers or similar devices, and aims to provide certain improvements therein.

Our invention is especially applicable to that type of stopper in which the valve seat is formed at the lower end of the socket member, and the latter is extended upwardly a considerable distance above the point of its connection with the neck of the bottle, suitable ports being provided for the entrance and discharge of water. In stoppers of this type the part which constitutes the stopper proper is designed to be screwed or otherwise moved upwardly until it passes the ports of the socket member, when the bottle is to be filled or emptied, there being no necessity of removing the stopper from its socket.

Our invention aims to provide an improved device of this class wherein the stopper is securely held in place at all times within the socket so that it cannot be lost or misplaced.

Our invention includes certain other features of improvement which will be hereinafter specified.

In the drawings which illustrate certain embodimentsof our invention, Figure 1 is acentral vertical section of the funnel and neck of a hot water bag of the usual construction having attached thereto a stopper embodying our inventionyFig. 2 is a view showing the parts of the stopper of Fig. 1 detached; Fig. 3 is a plan view of the cap; Fig. 4 is an elevation partly in section illustrating the method of applying the cap to the stopper; Fig. 5 is an elevation partly in section showing a modified form, and Fig. 6 is a plan of the cap shown in Fig. 5.

In the drawings let A designate a hot water bag of suitable construction having a neck a and a flaring mouth or funnel b.

The socket member Bis shown as formed of a sheet metal tube having an inturned flange c at its bottom adapted to form a valve seat, and a scrmv-threaded wall (Z to the outer side of which the neck a of the bottle is ulcanized. In thetype of stopper shown the socket member B is constructed so that it extends considerably above the point of its connection with the neck a as shown. The principal reason for this construction is that it enables the stopper C to be moved upwardly a sufficient distance to permit the free passage of water to the bottle through radial openings 6 formed in the sides of the socket member, without rcmoving the stopper from such member. The stopper C may be of any usual construction that shown having a sheet metal body f formed with screw-threads which engage those of the socket member B. At its lower end the stopper carries a disk of packing material 9 which is adapted to contact with the flange c of the socket mem ber, and close the opening therein. At its upper end the stopper is provided with a suitable handle it here shown as constructed of a piece of wire having its ends riveted to the upper wall of the stopper.

If the stopper C be left so that it may be withdrawn freely from the socket member, it is apt to be accidentally removed and misplaced or lost, notwithstanding the fact that it is not necessary to remove it in order to fill or empty the bottle. Difliculty has been experienced in providing an eflicient means for preventing such accidental withdrawal of the stopper. The cap or other means adopted for this purpose must have a restricted opening which is too small to permit the engaging shoulder of the stopper to work up through it, and the handle 72 must practically be made of considerably greater Width than such opening. On the other hand it is equally necessary to construct the parts so that the cap can be applied to and removed from the stopper. We prefer to use a cap D for this purpose which has a flange 6 adapted to engage a shoulder j formed upon the plug as shown in Figs. 1 and 2, the flange overlying the shoulder to such an extent that there is no possibility of working the stopper past the flange. The latter is also too wide to permit the cap to be passed over the handle h, the eflective opening of the cap being of less diameter than the width of the handle.

According to our invention we so form the handle and cap that the latter may pass freely over the former without any necessity of changing the fixed proportions of the parts, and without reducing the Width of the flange so as to render it ineflicient to limit the movement of the stopper. This may be accomplished in various ways, but we have shown in the drawings the construction which we prefer to employ. In this construction we enlarge the opening in the cap ir one direction byforming oppositely arranged notches z" in the flange i as best shown in Fig. 3. With the type of handle shown we have found that by tilting the cap relatively to the handle as shown in Fig. l, the cap may be passed over the handle even though its opening is considerably smaller than the width of the handle. This permits us to reduce the size of the notches and thus avoid weakening the cap. Obviously by giving the handle different proportions the necessity of notching the can may be avoided.

The cap may be applied to the socket member by any suitable form of connection which will permit it to be attached thereto and removed therefrom, but we prefer to adopt the construction shown in Figs. 1 to 4. In this construction the cap is formed with a vertical flange Z which is adapted to en'- gage a projection upon the socket member. As shown the latter is provided with an outwardly extending circumferential bead m, and theflange Z is provided with a corresponding internal groove a. The flange is preferably slotted at intervals to permit it to more easilv spring into place.

The socket member may be screwthreaded along its entire length if desired, but in the present construction we prefer that the upper part of such member be constructed with a plain cylindrical wall of suflicient length relatively to the screwthreaded portion of the stopper to permit the latter to leave the threads before the stopper contacts with the flange z' of the cap. By this construction the stopper rotates idly as it bears against the flange, thus avoiding the lifting tendency upon the cap which the stopper would exert-if it were still in engagement with the threads of the socket member.

In Figs. 5 and 6 we have shown a modified form of retaining cap. In these figures the socket member (here lettered B) is screw-threaded throughout its entire length, and the cap D is formed with a screwthreaded flange Z to adapt it toscrew on the socketmember. In some instances it is desirable to form notches p in the flange Z to receive the handle in separating the parts.

Although we have described in detail certain embodiments of our invention, we do not wish to be limited thereto, as various modifications may be made therein without departing from our invention.

What we claim is 1. In a bottle stopper, the combination of a socket-member having a screw-threaded portion, and a plain portion above said screw-threaded portion of greater diameter than said screw-threaded portion, a screwthreaded stopper, and a flange-member adapted to engage said plain portion of said socket-member to retain said stopper in said socketmember, said flange-member and socket-member having inter-engaging resilient locking means.

3. In a bottle stopper, the combination of a socket-member having a screw-threaded portion and a plain portion above said. screw-threaded portion of greater diameter than said screw-threaded portion, a screwthreaded stopper, and a flange-member adapted to engage said plain portion of said socket-member to retain said stopper in said socket-member, said flange-member and socket-member having inter-engaging locking means, said means comprising a bead on one of said parts and resilient means adapted to engage said bead on the other of said parts.

4. In a water bottle stopper, an elongated socket member, a stopper movable longitudinally therein. said socket member having an opening below said stopper when the latter is in its extreme outer position. said stopper having a handle connected to its upper end and a cap adapted to engage said socket member having an opening therein through which said stopper is adapted to proiect and be grasped to be moved in said socket to open and close the same, said opening having a. dimension smaller than the breadth of said stopper, whereby the outward escape of said sto er from said socket is prevented. and having a greater dimension than a dimension of said handle in a tilted position thereof, whereby said handle mav pass through said cap to detach said handle and cap, said handle having portions greater in breadth than the greatest dimension of the opening in said cap.

5. In a water bottle stopper, a socket memher, a stopper screwing therein, a cap conmaaeee nected to said member, andhaving a central openin and a flange surrounding such opening and overlying a portion of the stopper to prevent withdrawal of the latter, said stopper having a handle of .greater width than the diameter of said opening,

. and said flange having recesses adapted to screw-threaded portion, a screw tit 7. In a bottle stopper, the combination of a socket-member having a screw-threaded portion, and a plain portion above said screw-threaded portion of greater diameter than said screw-threaded portion, a screwthreaded stopper, and means for retaining said stopper within the plain portion of said socket-member, said means comprising an inwardly projeetingflange on said socketmember.

In witness whereof, we have hereunto sied our names in the presence of two suseribing witnesses.
